This invention relates to improvements in zz trolley pole sockets and has among other obects to provide a new and improved adjustable trolley pole socket-for reel and'trolley'v gathering locomotives operable. in thin' seams of.coal. -f Formerly trolley poles used on mine locomotives have been supported for pivotal movement about a vertical axis with the base of the trolley pole on a level with the top ofthe locomotiveso that th'e trolley pole'may be completely reversed if desired; A trolley pole so supported' projects above the deck of' the locomotive when the pole is in an'inoperative position and the locomotive ismovin'g in low sections of the mine on power obtained from the cable reel. The device ofmy invention provides a trolley pole socket which supports the trolley pole so-that the base thereof is on a level with the top deck of thelocomotive when the trolley pole is in an operative position, and lowers the entire'trolley pole below the deck of the locomotive when'the trolley pole is in an inoperative position and the locomotive is traveling in low parts of the mine on power obtained from the'cablereel.

My invention may be more clearly understood with reference to the accompanying drawings wherein: I v

A vertically extending guide groove30isformed in the cylindrical guide 28and-is adaptable to receiveia studu31 integral with the socket 23 to prevent turning of said socket within said support.

Flexible means are provided for vertically moving the socket 23 within the cylindrical guide 28 which means herein comprises a cable 32 having one end fixed in the support member 26. Any well known meansmay be used to hold the cable 32 to the support menuber 26, but as herein shown a threaded clampingmember 33 is fixed on the end of the cable 32, and a nut 34 is threaded on the end of said clamping member, and abuts the outer side of said support member. The cable 32 extends downwardly from the. clamping member 33 around a pulley '35 journaled' on the stud 31 to rotate about an axis parallel to the longitudinal axis of the locomotive. From thence the cable 32 extends upwardly over a' pulley 36 supported in the support member 26 on a shaft 37 near the upper end thereof to rotate about an axis extending transversely of the locomotive frame. The cable 32 then extends forwardly along the locomotive frame 13 to a point where it may Ll, be conveniently reached by the locomotive operator. A hand grip 4:0 is provided on the forward end of the cable 32 and stops 41 and 42 are fixed'to the locomotive frame. to engage thehand grip 40 and hold the trolley pole socket 23 in an elevated operative position or allow said trolley pole to rest in a lowered inoperative position.

In Figures 1 and 3 it may be seen that when the hand grip 40 is engaged by the stop 42 that the socket 23 is in an elevated position and that the base 21 of the trolley pole support is on a level with the top deck of the locomotive so the trolley wheel 18 may engage the trolley wire and so that thetrolleypole 11 may be moved about both a vertical and horizontal axis to enable the trolley wheel to follow the wirewhen the locomotive istraveling on. an irregular track around sharp turns as well as when on a J straight track. It may also be seen that when the hand grip is engaged by thestop 41 that the trolley pole support 20 is below the deck of the locomotive, and that when the trolley pole 11 is in asubstantially horizontal position, and engaged by a hook 43 to hold it in such a position, that the entire trolley mechanism is below the top deck of the locomotive, thus allowing the locomotive to travelinto low rooms or entries on power obtained from the cable reel 12.

It may thus be seen that an adjustable socket for a low vein combination cable reel and trolley locomotive has been provided which supports thetrolley in an elevated position when in operation to allow a maximum horizontal and vertical movement of said trolley pole and in a lowered position below the deck of the locomotive when inoperative,

" which allows the locomotive to travel in coal support'havingguide' walls therein, a socket guided in said gu de walls, agulde groove within'said walls, a stud having. connection with said socket nd guided by said guide groove, a pulley on saidstud, and a flexible member having connection l withf said pulley intermediate its ends for vertically moving said socket within said guide Walls.
